Mitotic cell divisions increase cell number while faithfully distributing the replicated genome at each division. The embryo is a powerful model for eukaryotic cell division. Nearly all of the genes that regulate cell division in are conserved across metazoan species, including humans. The pathways tend to be streamlined, facilitating dissection of the more redundant human pathways. Here, we summarize the virtues of as a model system and review our current understanding of centriole duplication, the acquisition of pericentriolar material by centrioles to form centrosomes, the assembly of kinetochores and the mitotic spindle, chromosome segregation, and cytokinesis.
有丝分裂细胞分裂增加细胞数量,同时在每次分裂时忠实地分配复制的基因组。胚胎是真核细胞分裂的有力模型。几乎所有调节细胞分裂的基因在后生动物物种中都被保守,包括人类。这些途径往往被简化,有利于解析更冗余的人类途径。在这里,我们总结了作为模型系统的优点,并回顾了我们目前对中心粒复制、中心粒获得构成中心体的周围物质、动粒和纺锤体的组装、染色体分离和胞质分裂的理解。
